Bed carrying frame

ABSTRACT

A bed carrying frame comprises corner members and rails readily assembled and disassembled. The corner member has a channel to receive the rail and a recess to receive a locking means attached to the rail. The locking means has walls which engage corresponding walls of the recess to wedge the locking means and rail in the recess and channel and thereby preclude longitudinal and transverse movement of the rail with respect to the corner member.

[57] ABSTRACT A bed carrying frame comprises corner members and rails readily assembled and disassembled. The corner member has a channel to receive the rail and a recess to receive a locking means attached to the rail. The locking means has walls which engage corresponding walls of the recess to wedge the locking means and rail in the recess and channel and thereby preclude longitudinal and transverse movement of the rail with respect to the corner member.

10 Claims, 4 Drawing; Figures PATENTEUJM 16 1973 BED CARRYING FRAME This invention relates to a bed carrying frame and more particularly to a corner member and rail combination for a bed carrying frame.

Beds generally comprise a bed carrying frame, a box spring unit and a mattress. The box spring unit is placed in the frame and the mattress is placed upon the box spring unit.

It is an object of the present invention to provide a bed carrying frame which may be readily assembled and disassembled. It is a further object to provide a corner member and rail combination for a bed carrying frame which may be easily assembled and disassembled.

These and other objects more apparent hereinafter are accomplished in accordance with the present invention by the combination of a corner member and rail wherein the rail has locking means adapted to slidably fit into and engage the corner member in such a manner that the rail and corner member are locked together to prevent longitudinal and transverse movement of the rail. The rail and locking means easily slide out of the corner member to disengage or unlock these parts.

The invention both as to its organization and method of operation taken with further objects and advantages thereof will best be understood by reference to the following description taken in conjunction with the following drawings in which:

FIG. 1 is a perspective view of a bed carrying frame embodying the features of the present invention;

FIG. 2 is an enlarged fragmentary plane view of a portion of the bed carrying frame of FIG. 1;

H6. 3 is a cross-sectional view of the bed carrying frame taken along line 3-3 of FIG. 2; and

FIG. 4 is a cross-sectional view of the bed carrying frame taken along line 4-4 of FIG. 2.

Referring now to the drawings and more particularly to FIG. 1 there is illustrated a bed carrying frame embodying the features of the present invention and indicated generally by reference numeral 10. The bed carrying frame comprises end rails l2, l4 and side rails l6, 18 which are attached to comer members 20 in accordance with the features of the present invention. The rails 12, 14,16, 18 and comer members 20 may be easily assembled and disassembled. When assembled in accordance with the present invention these .rails are firmly secured to the corner members 20 and longitudinal or transverse movement of the rail is precluded by virtue of the particular locking means employed by the present invention. The corner members 20 each have a castor 22 to permit the bed carrying frame 10 to be readily moved after the box spring unit and/or mattress have been placed on the frame 10. Each corner member 20 has a flange 23 extending about the corner of the member 20 to prevent the box spring unit from slipping off of the bed carrying frame 10 in either a longitudinal or transverse direction.

Referring now to FIGS. 24 also the rails 12, l4, l6, 18 in this instance are angle irons 24 to which are attached locking means indicated generally by reference numeral 26. The corner member 20 has a channel 28 adapted to receive the downwardly extending leg of the angle iron 24 and a recess'30 communicating with said channel 28 adapted to receive the locking means 26.

Suitable means, in this instance, rivets 32 are used to attach the locking means 26 to the downwardly extending leg of the angle iron 24. The locking means 26 is a metal plate or bracket forming two downwardly converging end walls 34 and 36 and a surface 38 intermediate thereof which slants upwardly and outwardly away from the rail..The recess 30 forms downwardly converging end walls 40 and 42 and a surface 44 intermediate thereof which slants downwardly and inwardly toward the channel 28.

The rail and the corner member 20 are attached by placing the rail in the channel member 28 and the locking means 26 thereof in the recess 30 and forcing the rail and its locking means downwardly into the channel 28 and the recess 30, respectively. As the 1 locking bracket moves downwardly into the recess 30 claims all such modifications and improvements the end walls 34 and 36 come into contact with the end walls 40 and 42, respectively, of the recess 30 and the locking bracket becomes wedged between the walls 40 and 42, which prevents movement of the rail along its longitudinal axis. At the same time the surface 38 of the locking bracket contacts the slanting surface 44 of the recess and wedges the locking bracket and rail within the recess 30 and the channel 28, which precludes movement of the rail in a transverse direction. Firm locking of the rail and the corner member can be assured by striking the rail with a hammer or other suitable means to firmly wedge it into the corner member 20. Likewise, the rail may be readily detached from the corner member by striking it in the opposite direction.

Similarly, all ends of the side and end rails may be attached to and disconnected from the corner members 20 of the bed carrying frame 10. llt will be understood that the same locking arrangement may be used with rails having rectangular-tubular configurations, triangular-tubular configurations'and the like.

While the embodiments described herein are at present considered .to be preferred, it is understood that various modifications and improvements may be made, and it is intended to cover in the appended as fall within the true spirit and scope of the invention.
